Re: We all need less stress...
"Hydraulics is just as controllable as Steam, if anything, probably more so"
The problem being that you need to develop a lot of power very quickly. Steam has the advantage that an adequate reservoir can be created fairly easily, and work has been done on steam flow profiles and valve gear since the 19th century, when a lot of work was done on getting even turning moment on large ship engines. How do you create the equivalent reservoir for an incompressible fluid? Compressed air? Really big electrically powered pumps? In either case you have to rely on a method which leads you to wonder "well, why add the complexity of the hydraulics then?"
